Im in GA Atlanta too. First time owning a car in GA so I don't know how i am going to survive. I have a black car with black interior with 3M Carbon Tint 30%.
But I usually park under the roof so I might not have problem.
I would never give up my black interior

 

i have black interior in so cal with 5% rear tint and 15% front and just jump right in my car and go.. seats and steering wheel are fine thanks to the tint.. i wouldn't even say my seats get warm..
